Consider something like this for now - https://www.sustainable.co.za/axpert-mks-3-24-3kva-3000w-24v-hybrid-inverter.htmlCape Town. I've been mulling over a range of ideas:
- a smallish setup that will cover a couple of lights, the router, fibre, PC (or flatscreen and PS4),
- spending a bit more on higher quality equipment with room to upgrade in future if need be
- a full on solar install
The problem is it also depends on your outlook of the future of SA. If one thinks that we are going to end up like Zimbabwe or Nigeria where they have extended blackouts, then options 2 and 3 are the way to go.
If one expects a couple of years of intermittent load shedding, then its the first option.
Which is a 24V inverter, so you can get away with 2x 12V Lead Acid batteries for now, and add solar later if needed or change out the batteries for Lithium.
It's small enough to save you about 6-8K on the inverter alone, will save you a bit on initial battery outlay (don't need 48V) and it's big enough to power fridge / freezer along with all your lights, TVs, routers etc. if necessary and it's pure sine wave.
If in 5 years when your batteries die and you have a better idea of the shortcomings (if any) you can resell the inverter and upgrade to a 5kVA or larger and also upgrade your batteries.
IF Eskom performs a miracle and comes right, you didn't put R100k into a system you hardly need. If Eskom does not improve - you will still have a pretty decent inverter and possibly even solar by then.
